Mixing brands of poly
We used water-based Olympic satin poly on our walnut site-finished floors a few months ago. It has been absolutely dreadful as far as scratches go. They're on the finish only, not into the wood, but when the sun shines on the floors they look all scratched up. And we're not talking kids and dogs running around (we have none), we're talking the wheels on the vacuum cleaner leave scuff marks.
Reading through a lot of posts, I wish we had used Bona Traffic. But we didn't, so I'm wondering if we can put a coat of it over our existing floors without sanding the existing poly completely off.
Can you "mix" poly by putting one brand over a different one, if they're both water based?
